For Loop in Programming Language

For Loop

The for loop is one of the most commonly used loops in programming. It is typically used when the number of iterations is known beforehand. The syntax generally includes an initialization, a condition, and an increment/decrement operation.

Which loop to use? For or While

Language: Java

public class Main {
    public static void main(String[] args) {
        for (int i = 0; i < 5; i++) {
            System.out.println("Iteration: " + i);
        }
    }
}

Language: Python

for i in range(5):
    print("Iteration:", i)

Language: C++

#include <iostream>
using namespace std;

int main() {
    for (int i = 0; i < 5; i++) {
        cout << "Iteration: " << i << endl;
    }
    return 0;
}

Language: C#

using System;

class Program {
    static void Main() {
        for (int i = 0; i < 5; i++) {
            Console.WriteLine("Iteration: " + i);
        }
    }
}

Language: JavaScript

for (let i = 0; i < 5; i++) {
    console.log("Iteration: " + i);
}

Language: PHP

<?php
for ($i = 0; $i < 5; $i++) {
    echo "Iteration: " . $i . "<br>";
}
?>

Language: Swift

for i in 0..<5 {
    print("Iteration: \(i)")
}

Language: Go

package main
import "fmt"

func main() {
    for i := 0; i < 5; i++ {
        fmt.Println("Iteration:", i)
    }
}

Language: Ruby

for i in 0...4
  puts "Iteration: #{i}"
end

Language: Kotlin

fun main() {
    for (i in 0..4) {
        println("Iteration: $i")
    }
}

Language: X++

static void ForLoopExample(Args _args)
{
    int i;
    
    // For loop that runs 5 times
    for (i = 1; i <= 5; i++)
    {
        info(strFmt("Iteration: %1", i));
    }
}
